When we count objects, we can say
-
The number of apples is two.
-
The number of oranges is three.
I am wondering how to combine these two sentences.
Can I say that:
The number(s) of apples and oranges is five.
I want to know if I need "s" in numbers (because I am talking two different numbers).
Or can I say:
The number(s) of apples and oranges are different.
The number(s) of apples and oranges are two and three.

The expression "the number of" emphasizes a precise quantity. It is used when the exact number is important, not just the fact that there are many (it would be a number of then) and it takes a plural noun followed by a singular verb. So it would be:
This agrees with the basic rule of Subject-Verb Agreement:
A singular subject (here - the number) takes a singular verb (here - is).
